Private Clouds

The Pros and Cons of Private and Public PaaS

Grazed from Virtualization Practice. Author: Mike Kavis.

I just returned from attending the Cloud Expo in New York City this week. The conference was dominated by private and hybrid cloud topics. There were several private Platform as a Service (PaaS) vendors attending whom I spent a great deal of time talking to as I walked the floor. It seems these days that many enterprises default to private and hybrid clouds and therefore insist on private PaaS as well. It is critical that consumers of PaaS services understand the pros and cons of both public and private PaaS before making a commitment to a PaaS deployment model.

Public PaaS

Public PaaS solutions are platforms that run on the public cloud. The first PaaS solutions in the market place dictated both the stack that the code would be written in and the location of the datacenter that the code would be run on. For example, Force.com requires a proprietary language called Apex, and all of the Apex code runs on Force.com’s datacenter. Google’s PaaS forces developers to write in Python and runs the code in the Google datacenters. Microsoft’ PaaS requires .NET and runs in their datacenters...

ownCloud Enhances Private Cloud File Sharing for Android, iOS

Grazed from The Var Guy. Author: Christopher Tozzi.

What does it mean to have a cloud of one's own? Most of us would probably be satisfied with just the basics: Automatic file syncing, easy sharing features and efficient, Web-based access to data. But ownCloud, the open source cloud infrastructure project with humble beginnings, now offers much more, as the slew of innovative features in the most recent release of its mobile Android and iOS apps shows.

By offering an open source platform that lets individuals and enterprises build file-syncing and sharing infrastructures on their own hardware or in a private cloud, ownCloud has always stood out in a competitive niche where most other products were proprietary or subscription-based. But in its early days—and even after the launch of a commercial entity, called ownCloud Inc., to provide services related to the open source ownCloud software—ownCloud's feature set remained pretty basic...

Private PaaS eases enterprise governance, cloud security concerns

Grazed from TechTarget.  Author: Alex Barrett.

Concerns surrounding security and governance are prompting some Platform as a Service players to offer their wares on private infrastructure, not just the public cloud.   "Whether it's for data sovereignty or governance reasons, some of our customers tell us PaaS must be behind their firewall," said ActiveState's Copeland. "They say, 'There's no way we're putting our data on the public cloud,'" he said.

Implementing Platform as a Service (PaaS) in-house can also lay the groundwork for future use of public PaaS, he said. Hewlett-Packard used ActiveState Stackato in-house, and decided to license it as part of its HP Cloud Application Platform as a Service running on top of OpenStack, currently in beta. "That provides us with a common infrastructure stack that we can deploy on both public and private platforms," said Dan Baigent, HP Cloud Services senior director for business development...

Preparing Your Business For Private Cloud Migration

Grazed from Forbes. Author: Andy Maier.

Many businesses have not transitioned to cloud computing due to fears about the “openness” of the public cloud. Businesses and IT departments worry about losing control of their data, cloud security and sharing data space with other companies. An alternative to the public cloud platform model is private cloud.

Difference between Private Cloud and Hybrid Cloud

Many business professionals and IT admins are still confused about the difference between hybrid cloud and private cloud. A hybrid cloud solution involves both the public and private cloud. Basically, these deployments use a combination of public cloud with private or dedicated infrastructure...

Private And Public Cloud Migration Standards

Grazed from CloudTweaks. Author: Salam Ul Haq.

Ever since cloud computing has seen mainstream adoption, the ability to migrate data between public or private clouds is becoming a key concern, especially due to the large size and the cost involved in the switch. The first question that comes to mind when discussing cloud migration is if there are any cloud standards that will ensure interoperability? This is because in the absence of such frameworks, the effort of translation or manual data transfer operations might exceed budgets, especially for large public clouds.

Hence it is essential to understand if there are any interoperability standards that may help in the migration. Another key point is to understand the reasons behind a cloud migration whose assessment will justify such a shift.We can say that cloud interoperability is still a topic under discussion by various cloud providers including HP, Red Hat, Rackspace, Citrix etc. The forum known as ‘OpenStack’ is promoting to build an open platform with open standards that various cloud providers can integrate in their systems making them more interoperable...

5 tips for avoiding private cloud failures

Grazed from Network World. Author: Christine Burns.

According to Piston Cloud Computing's CTO, the rate at which his customer’s pilot projects turn into production private clouds is pretty typical of most OpenStack-based providers – and it’s pretty low. “Roughly for every 20 pilot projects we open up, we see one of them make it into production,” says Josh McKenty, who prior to founding the Seattle-based Piston, worked at NASA and served as a technical lead on the project that evolved into OpenStack, one of three open source infrastructure as a service (IaaS) platforms vying for enterprise attention.

So why do the other 19 drop off? Good question, admits McKenty. According to analysts, developers and cloud practitioners, the answer turns on miscommunication (between corporate IT department and their potential “customers”), dependencies (on beloved features of gear sitting in the data center or on the network) and unruliness (of applications not built to run on the cloud at inception)...

Private Platform as a Service Enables DevOps

Grazed from InfoQ.  Author: Aslan Brooke.

Gene Kim, author of The Phoenix Project, discussed how private Platform as a Service (or PaaS) fits into DevOps with Steven Witkop, John Skovron, and Elis Booker in early may. Elis Booker facilitated the discussion with questions about DevOps, dispelling misconceptions about private PaaS, and how to get started with private PaaS. Each panelist contributed a distinct view on the topics to create a multifaceted message about private PaaS.

Gene Kim provided insight into the problem domain by describing the theory of constraints as it applies to DevOps and listing constraints in developing software that should be addressed in sequence:

  1. Provisioning of environments/deployment (for which PaaS is a solution)
  2. Test Setup, Test Runtime
  3. Architecture Changes
  4. Development/Product Management...

Worried About Your Data In The Cloud? Stop Whining And Get Your Own Cloud

Grazed from Forbes. Author: Karsten Strauss.

We knew this was going to happen. We’d heard about the “forthcoming era of cloud computing” as Bill Gates stepped away from Microsoft MSFT +0.46% in 2008 and the company’s then mission seemed to be to adjust to post-PC realities. Steve Jobs tried to sucker Dropbox co-founder Drew Houston into selling him the cloud-sharing company in 2009 prior to Apple AAPL +1.47%’s eventual release of iCloud.

Now that we’re knee-deep in the cloud, some users are getting a little bit nervous about having their data stored somewhere else, overseen by who knows who. It’s this uncertainty and nervousness that StoAmigo’s CloudLocker is built on. For those for whom Google GOOG +0.27%, Amazon, Microsoft and Dropbox’s server farms are too far away for comfort, CloudLocker gives you your own private cloud...

Public, Private, Hybrid: Why it Takes All Types to Answer 'What is Cloud?'

Grazed from Forbes. Author: Ken Owens.

Ask anyone in technology circles, “What is cloud?” and you’ll get a handful of different answers. But the responses will likely all relate back to three key models: Public cloud, private cloud and hybrid cloud. Businesses need to be aware of how these models can fit into their strategies. We know from this independent survey conducted by research firm Vanson Bourne for Savvis that IT leaders are shifting their views on cloud computing – and broader IT outsourcing. About 60 percent of leaders agreed that owning IT infrastructure wasted resources, compared to just 38 percent two years earlier.

Not surprisingly, given these figures, a huge percentage of organizations have shown an air of regret around the purchasing of IT equipment. Equally significant, as these organizations shift to cloud and outsourcing, we’re seeing CIO mindshare now center on more strategic concerns...
